Why Is My MacBook Not Showing Up the USB Devices?

While it’s impossible to instantly figure out why the USB devices are not showing up on your Mac, here are a few of the common reasons.

The Device Is Not Properly Plugged In

Whether you are using an HDMI or a USB cable, if it’s not properly plugged in, it won’t appear on your Mac. Check your plugged cable and make sure that it is plugged in properly.

Faulty Cable or Damaged USB Port

Assuming that you’ve plugged in the USB device correctly and it’s not loose, there is a chance that the cable could be at fault or there is a hardware issue with the Mac. In this case, try to connect the device with another cable or to a different port.

Incorrectly Formatted Drive

Unfortunately, all the external drives are not optimized for Macs. So, it might be possible that the device you are trying to connect is only suitable to interact with Windows.
